Process Analyzers
The Industry Standard HCDP/WDPAnalyzer
The Condumax II fulfills the demands of natural gasproducers and
pipeline transmission companies for reliableon-line monitoring of
natural gas hydrocarbon and water dewpoint.
Condumax II is the industrys analyzer of choice to
ensure conformance of these key gas quality parameters,from
production processing, through trans-continentalpipeline networks
into final distribution and utilization bymajor consumers such as
power generators. Throughoutthe midstream industry Michell
hydrocarbon dew-pointanalyzers are installed as permanent
analyzers, providingmeasurements six times every hour 24/7/365.
Transportable Condumax II for FieldValidation
The Condumax II Transportable addresses the furtherneeds of
natural gas users as the industry evolves. Withan increased
proportion of alternative fuel sources suchas biogas, and greater
reliance on LNG imports into gasnetworks which traditionally
received gas solely from fixedupstream producers, the attention to
ensuring accurate
measurement of dew point has never been more critical.This
increased complexity of supply chains has expandedthe number of
potential measurement points each requiringconformity to
specification. The Condumax II Transportableoffers the flexibility
to make investigative spot-checkmeasurements at any location, to
even the smallest and mostremote gas source. Furthermore, for the
gas producer, theCondumax II Transportable can be used to profile
individualprocess stages to ensure optimum efficiency.
Quality Assurance with a New TransferStandard
The Condumax II Transportable also enables establishedusers of
permanent on-line dew-point analyzers to carry outperiodic
comparative measurements in the field to verifymeasurement
performance against the certified factorylaboratory calibration of
the Condumax II to all users.
The Condumax II Transportable offers automaticmeasurements of
high sensitivity and objectivity whereverthey are needed in a
simple to use, self-contained, samplehandling, conditioning and
analysis package.
Sample Conditioning System
Complete integration of Condumax II Main Unit
System configuration for connection direct to
transmissionpipeline natural gas at typically 70 barg (1015
psig)pressure
Simultaneous water dew-point measurement at processpressure.
Integration of water dew-point sample flow in
series for analysis at full line pressure
Process pressure gauge, 100 barg (1450 psig) scale
Coalescing filter with by-pass needle valve and systemdrain
Sample gas pressure reduction via electrically-heatedregulator
for analysis of HC dew point at intermediatepressure
(cricondentherm condition), adjustment range upto 35 barg (507
psig) fitted (analysis pressure indicatedby Condumax II Main
Unit)
Sample flow control with armored rotameter
*To assure correct measurement performance ofthis system in
outdoor field use, the ambient air
temperature must be at least 5C (9F) above boththe hydrocarbon
dew-point temperature of the
process gas sample at the cricondentherm condition,typically 27
barg (391 psig), and water dew-point at
full process line pressure.
